Steadichlor tablets offer a simple and effective means of water chlorination without the need for complex dosing equipment. Steadichlor tablets dissolve in water to give a slow steady chlorine release. The dissolving time is approximately 4 hours in flowing water or 12-24 hours in static water.
Steadichlor tablets are prepared from calcium hypochlorite. In use, the tablets do not contribute any substances not normally present in treated mains water.
Steadichlor tablets offer an ideal means of chlorinating water in tanks, wells or small reservoirs: and waste water in tanks or effluent streams. The tablets should be used in accordance with standard chlorination practice depending on the water to be treated and the purpose of treatment.
Where chlorination is to be carried out to disinfect the water, a free chlorine residual of at least 1 mg/l should be achieved in the treated water. Note that it will normally be necessary to add a higher chlorine dose to satisfy the chlorine demand of the water.
The dosage of Steadichlor tablets should therefore be controlled in response to free chlorine test readings taken on the treated water. Testing should be carried out using Palintest DPD No. 1 tablets and a chlorine test kit.
